- Abstract
- This thesis studied the recording methodologies of conducting unannounced evacuation drills to enhance the understanding of evacuation behaviours and performance within the Complex Muon Solenoid (CMS) cavern at CERN. The primary objective was to validate the CMS underground evacuation simulation model for planned evacuation and compare various data collection methods.
An unannounced evacuation drill was conducted in the CMS cavern which capture data from 10 occupants through questionnaires, observation and video recording. The drill highlighted the discrepancies between self-reported behaviours and actual action which implicates the need for cross-verification of data. Key findings include an average pre-evacuation time of 55s.

An unannounced evacuation drill was conducted in the CMS cavern which capture data from 10 occupants through questionnaires, observation and video recording. The drill highlighted the discrepancies between self-reported behaviours and actual action which implicates the need for cross-verification of data. Key findings include an average pre-evacuation time of 55s.
Also, simulated scenario analysis by changing the behavioural and design factors such as occupant load, distribution, usage of lifts and emergency devices were studied which were based on CMS drill data and past studies. The model revealed variability in evacuation time across different scenarios, with coefficients of variation ranging from 21\% to 45\%. The adjusted evacuation model validated against the CMS drill.
Future works could focus on standardizing data collection method to aim establishing a mutual database for evacuation data comparison between different background. Exploring non-intrusive technologies such as RFID could enhance data accuracy by avoiding influence by observers. Moreover, refinement of CMS evacuation models on behavioural and design factors is needed to investigate. (Less)
